"No one can get close to them since the fire is still raging at the scene," he added, saying that there had been no casualties.

Kabul police director Gul Aghan Hashimi said a magnetic bomb had been used in the attack while a NATO-led International Security Assistance Forces spokesman said they were investigating whether the fuel was intended for foreign troops.

The Afghan interior ministry said initial investigations found that 200 trucks had been damaged.

The incident took place in Chawk-e Arghandi and comes as the Taliban steps up attacks with NATO forces due to complete their withdrawal from the country by the end of the year.

Taliban spokesman Zabihullah Mujahid said in a statement that fighters belonging to the group had carried out the destruction.

ISAF said on Friday a rocket attack at the United States' main military base at Bagram Airfield had resulted in "minor damages to equipment and one building".

It came just a day after Taliban insurgents fired rockets into Kabul airport, destroying the Afghan president's parked helicopter and damaging three other helicopters.

On Wednesday, a Taliban suicide bomber in Kabul killed eight military officers travelling on a military bus.

The attacks underlined security fears in the capital which has been relatively peaceful since the June 14 presidential runoff between Abdullah Abdullah and Ashraf Ghani.

Kabul has witnessed tense street demonstrations as the two candidates remain locked in a dispute over voter fraud which is threatening to derail Afghanistan's first democratic transfer of power.

US-led allies are eager to avoid a prolonged power struggle as they prepare to leave by December.

All NATO combat troops will exit by the end of the year, with about 10,000 US troops staying into 2015 if the new president signs a security deal with Washington.
